' HEATING UNIT.

Application mea october s, 1920. serial No. 415,470.

To all whom t may conce/rn.'

Be it known that I, LAWRENCE C. SoULE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Heating Units, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to improvements in heatlng apparatus and particularly to that type of apparatus used for factories, schools, and auditoriums and the like.

One of the objects of my invention is to provide a heating unit through which the air, either of the room, or fromthe outside, or both, may be passed over the heat emitting surface and heated before it is discharged into the room.

Another object of my invention is to pro vide a heating unit which may be readily as sembled, which will not only indirectly heat the air, but which also will have a certain amount of direct radiating surface.

Another object of my invention is to provide a readily assembled device in which the air as it passes therethrough will pass over or uwipe a large amount of heating surface. For the purpose of disclosing my invention I' have illustrated one embodiment thereof in the accompanying drawings in which,

Fig. 1 is a central vertical sectional view illustrating one embodiment of my invention,

Fig. 2 is a front elevation thereof,

Fig. 3 is a` sectional view taken on the line 3-3 of Fig. 1,

Fig. 4 is a rear elevation of the embodiment, and

Fig. 5 is a sectional view taken on the line 5 5 of Fig. 4.

In the embodiment illustrated, I provide a base 1 which is hollowand preferably rectangular in shape and provided with legs -u `edges of the sections on both the top and 1a to. suitably raise it from -the floor. The bottom of this base is partially closed by a wall 2, the top being open and having on the inner face of the sides thereof a horizontally disposed flange 3 which is somewhat below the top. One of the sides of the base is rovided with an opening surrounding which is a flan e 4 adapted to receive a conduit pipe 5. 's pipe leads to the outer air and the opening in the base is controlled by damper 6 pivotally mounted in position. A second inlet opening 7 in the bottom of the base is provided which opening is likewlse controlled by a damper 8, the two dampers. being connected by a link 9 so that they W1ll move in unison, the connection being such however, that as the damper 6 is open the damper 8 is closed and vice versa.

For operating the dampers, the pivot 10 on which the damper 8 is mounted is provided with an arm 11 arran ed on the exterior of the base which arm 1s adapted to be rocked back and forth by the operator to move the dampers to any desired position. This arm 11 is provided with a locking device for a positive setting of the dampers.

The air heating element of the heater un1t .comprises a flue composed of a plurality of sections 12, Fig. 5, mounted one on top of the other, and on top of the base, through which steam or hot water is adapted to circulate. The sections are all alike and each comprises a pair of hollow peripheral side members 13 connected at their ends to hollow peripheral cross heads 14. Extending between the cross heads 14 are parallel hollow ribs 15 which are oval shaped in cross section.

The ribs 15 are spaced apart and from one side member equidistantly although the space between the opposite side member and its adjacent rib is greater. An intermediate cross member 15a also connects the ribs and side members.

At a point equidistant from the side members there are provided nipple openings 16 by which each section of the apparatus is connected with the others so that the heating fluid after circulating through one section may pass into the next one above.

The side and end members as well as the ribs are preferably oval shaped as shown in Fig. 3 so that a minimum amount of resistance will be offered to the air as it passes through the sections. Around the outer bottom, as well as surrounding the nipple connections, there are provided fins 17 which form meeting edges when the sections are stacked one upon the other whereby the sides of the flue formed by the sections are l completely closed.

In4 assembling the apparatus a bottom section is laid upon the ledge or flange 3 in the base, the rest of the; sections are stacked one on top of the other, the iins 17 making a tight joint between the sections.l In stacking -the sections, every alternate section is reversed so that while the nipple connections 16 are in alignment the ribs are staggered with respect to one another, forming a tortuous path through the Hue for the air. Suitable nipples 18 connect the various sections together and the top section is provided with aconnection 19 forthe admission of steam or hot water, while the bottom section is provided with a connection 20 for the return How of the steam or hot water. On the top of this return connection an air vent pipe 37 is provided with a large opening air valve 38 on the end of the vent pipe. The heater construction insures quick venting of the entire heater.

Mounted upon the top of the Hue thus built up is a hood or cover, the base 21 of which is rectangular in shape and is provided with a flange 22 adapted to rest upon the top section of the radiating sections. One side 23 of the top or cover is provided with a suitable circular opening having an annular flange 24 surrounding the. same over which may be fitted a Hue 25 or if de` sired the Hue may be dispensed with.

A suitable bracket consisting of a verticallyextending brace 26 and a transversely extending brace 27 formed integrally with the side 23 and forming at their junction a bearing 28 is provided in the opening. 'Ihe rear side of the top or cover is arc shaped as at 29 and is provided with an opening covered by a removable plate 30.

Mounted on the cover 21 is a .suitable drivin motor 31, the shaft of which passes throug the plate 30 and the opposite end of which shaft is mounted in the bearing ,28. This shaft is provided with a blower fan 32, adapted to produce a forced draft through the heating unit.y It is obvious that instead of driving the fan 32 with electric motor 31 other means for operating the fan ma be provided. di.

e Whole unit thus constructed and comprising the top, base and Hues, is tied together by suitable tie rods 33 which pass through lugs 34 extending laterally from the top and bottom and are provided with nuts 36.

'llhe operation of the device is apparent. 'll-he unit is placed in any Adesired position and by means of the Hue 5 is connected with the outside atmosphere. rllhe steam or hot water is admitted to the `radiating sections and as the an.32 is operated, the air is drawn into the bot-tomof the base of the unit, passing up through the heating sectlons and, due to the staggered arrangement of the ribs thereof, w1pes across a large number of radiating ribs and Hnally passes out through the eduction opening in the top of the unit. If desired the room air may be re-heated by closing the damper 6 and opening the damper 8, or if desired the room air and freshair may be mixed by partially opening one of the dampers and partially closing the other. 'Ihe air current may be exactly reversed, if desired, by changing the direction of rotation of the fan.

It will be noted that in addition to the radiating surface provided for heating the air as it passes through the unit there is also provided a direct radiating surface on the exterior of the unit which aids in heating the air of the room.
